Question

A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 15.0 m/s when it reaches the end of the ramp, which has length 129 m.
a) What is the acceleration of the car?
b) How much time does it take the car to travel the length of the ramp?
c) The traffic on the freeway is moving at a constant speed of 15.0 m/s . What distance does the traffic travel while

Answer 1

Hi I will try to help you with this hang on one second please!:)

Answer 2

To get the distance the traffic travels use distance traveled = speed x time [because the traffic speed is constant]

so distance traveled by the traffic = 23.0 m/s x 10.4 s = 240 m [I used the full calculator answer from the time calc ... but if you use the rounded 10.4 it's 239 m (to 3 sig figs)]

Answer 3

Does this sound ok? do you understand or do you want me to just telly ou the answer lol?:D

Answer 4

Answer is a

A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 23.0 m/s when it reaches the end of the ramp, which has length 120 m.The traffic on the freeway is moving at a constant speed of 23.0 m/s. What distance does the traffic travel while the car is moving the length of the ramp?

the answer is both acceleration and time.... Does this make any sense?

Are you there?? ....... LOL....;D
